	* src/sheet-style.c (sheet_style_cache_flush): add 'all' flag to
	signify a hard vs. soft flush, freeze hash when it is a nice size. Do
	not bother destroying the hash table.
	(sheet_mstyle_compute_from_list): kill debug in inner loop + add another
	short circuit. (calc_grown_range): Spread the range better near the
	edges.

	* src/mstyle.c (mstyle_do_merge): simplify + add vital short circuit for
	factor of 2 speedup on blank regions. (mstyle_get_*): kill redundant NULL
	preconditions.

	* src/main.c (gnumeric_main): add the tests again.

	* src/mstyle.c (mstyle_do_merge): Use pointer increment to kill mul in
	inner loop. (mstyle_element_ref): take a pointer.

	* src/sheet-style.c: Clean internals a lot, kill the nasty dereference
	macros, hash on CellPos to decrease memory usage.

	* src/dialogs/dialog-cell-format.c (draw_format_preview): Clip the
	sample down if it is a massive string to stop the dialog from becoming
	stupidly wide.

Fix for OLE to kill assertion for a vicious file corruption case.
